Introduction

- More than 230,000,000 migrants, worldwide
Movement models
Zelinsky’s Mobility Transition Model – Links stages of movement to development.
Zelinsky’s Mobility Transition ModelPhase 1 – Pre Modern – Ancient world, slow growth movement to cities.
Phase 2 – Early Transition – Massive movement to cities.
Phase 3 – Late Transition - Massive but slackened movement to cities.
Phase 4 – Advanced Society – Cities have grown and more have appeared. Movement to cites is leveling off.
Phase 5 – Future Super-advanced society – Countryside mostly gone, movement inter city now.
Movement models
Stouffer’s Intervening Opportunities - # of Migrants is related to # of opportunities.
“The number of persons going a given distance is directly proportional to the number of opportunities at that distance and inversely proportional to the number of intervening opportunities.”
Movement models
Lee’s Laws of Migration – 4 factors that make people migrate.
1. Factors linked to destination.
2. Factors associated with the area of origins of migrants.
3. Obstacles between origin and destination.
4. Personal Factors.
Essentially: push and pull factors
Migration defined
Textbook discusses movement vs. migration
- Cyclic movement
- Periodic movement
- Migration
All three involve mobility/movement, but differ in regards to permanence.
Movement
Cyclic Movement: short periods away from home.
e.g.
-Your daily routine (home-school- work- home)
- Nomadism: moving from place to place
Cyclic movement – activity spaces
Daegok (home)
KMU(school)
Downtown (work)
Cyclic movement – activity spaces
Nomadic life in Mongolia
Movement
Periodic Movement: long periods away from home.
e.g.
- Attending university in another city
- Military service
- Transhumance
- Migrant workers (e.g. foreign “3D” workers in Korea)
- Canadian oil field workers
Periodic movement – oil workers
6 months(home)
6 months (work)
Movement
- Cyclic Movement: short periods away from home.e.g. your daily routine (home-school-home)
- Periodic Movement: long periods away from home.
e.g. attending university in another city Canadian oil field workers
Only thing these two types of movement have in common with migration is just movement. People who migrate may never return to their origin.
Migration
Movement that results in permanent relocation across significant distances.
- Can involve an individual, household, or larger group to a new location outside the community of origin.
- The mover(s) may never return home.
Types of migration
International Migration – also called external migration. Move from one country to another.
When someone migrates out of a country = emigrant.
When someone migrates into a country = immigrant.
Internal Migration – move within a country.
Types of migration - mobility
Mobility depends on several factors (social, economic, technological).
Internal migration: Overall trend is rural to urban, but depends on the country (e.g. Peru vs. U.S. vs. China).
Reasons for migrating
Types of migration:
Forced Migration – involuntary move. - e.g. Atlantic Slave Trade
Today: counter-immigration
Voluntary Migration – choices or options make the migrant choose to move to the land.
- e.g. Colonists, Me
- Push and Pull factors,

Laws of migration
1. Every migration flow generates a counter-migration. e.g. – Colonists and Natives or city gets too crowded.
2.Majority of migrants move a short distance.
3. Migrants who move long distances usually move to big cities.
4. Urban residents are less likely to migrate than rural folk.
5. Families are less likely to make international moves then young adults.
Reasons for migrating – Gravity model
The gravity model is used to predict the movement of people, commodities, and ideas between two places.
- Larger places attract people, ideas, and commodities more than smaller places.
- Places closer together have a greater attraction.
Reasons for migrating – Push & Pull
Push factors – factors in “leaving” a place.
- usually more accurately perceived.
Pull factors – factors in “going” to a place.
- often vague (sometimes “fantasy”)
related to distance decay: farther you move away from your origin, may be harder to function in your new home. e.g. – culture, language.
Reasons for migrating – Push & Pull- Economic conditions
- Power relationships (gender, ethnicity, money)
- Political circumstances
- Armed conflict, civil war
- Environmental conditions
- Culture and traditions
- Technological advances
Push & Pull – economic conditions
- Haiti, U.S.
Push & Pull – power relationships
- Cultural perceptions
Push & Pull – political circumstances
e.g. Vietnamese “boat people” (almost 800,000)
Push & Pull - Armed conflict, civil war
Rwanda Syria
(>2,000,000) (approx. 3,000,000)
Push & Pull – Environmental conditions
Hurricane Katrina (2005) – city of New Orleans – 40% popn.
Reasons for migratingKinship links – family or friends find success in foreign land, motivates you to do the same there.
Chain Migration – kinship links expand, chains of family and friends communicate to others from their original homeland to migrate over. Groups of people migrate.
Immigration waves – swells in migration from one origin to the same destination.
Next class
Where are people going?
Governments (and conflict) and migration.
Before next class
There is one more short reading to do.
- There will also be some supplemental readings, but they are optional and you will not be tested on that material.
